- AEDP assumes people carry a built-in drive to heal and grow, which it calls transformance.
- Its central move is undoing aloneness: hard emotion is felt with a safe, engaged therapist.
- With that help, blocked core emotions are felt in a regulated way until they complete.
- Then the client reflects on the change itself, which deepens it.
- The aim is flourishing, not only fewer symptoms.
Why it matters
- For people with childhood attachment trauma and the therapists who treat them; it shows how a therapy with psychodynamic roots can put emotion and healing at the centre.
Key facts
- In short
- An experiential, relational therapy that processes trauma-related emotion to completion2
- Developed by
- Diana Fosha, who trained with Habib Davanloo, developer of intensive short-term dynamic psychotherapy1
- Started
- 2000, when Fosha named it and set it out in The Transforming Power of Affect7
- Core idea
- Transformance: an innate drive to heal and grow, released in a safe relationship1
- Draws on
- Attachment theory, interpersonal neurobiology, affective neuroscience, emotion theory and body-focused approaches2
- Used for
- Transdiagnostic; especially adults affected by childhood attachment trauma and abuse1
- Typical length
- The outcome studies used 16 sessions2
- Evidence
- Naturalistic pre-post studies with large effects; no randomised trial of AEDP itself listed4
How emotion is understood
-
Core affect3
Built-in, bodily, universal emotional experiences, such as categorical emotions and attachment strivings, that are adaptive once fully processed.
-
The triangle of experience3
A map from short-term dynamic therapy: defences (D) and inhibiting feelings such as anxiety (A) block access to core affect (E). It shows where the client is right now.
-
Transformance3
The overarching motivational force towards positive change; even in the first state, glimmers of it show up beside the defences.
-
Undoing aloneness2
Overwhelming emotion faced alone gets blocked; felt in the presence of a "true other", it can be processed and healed.
-
Transformational affects3
Change itself brings feelings: relief, pride, grief for the self, gratitude, and trembling excitement. AEDP names six kinds and works with them.
Examples: the triangle and the states in one person
-
Core emotion (E)3
Illustration: a client talking about a father who never came to her school concerts starts to feel sadness rising, one of the core emotions the glossary lists (sadness, fear, anger, joy, excitement, disgust).
-
Anxiety (A)3
Illustration: as the sadness rises her chest tightens and she feels a wave of nervousness: the inhibitory affect at the top of the triangle, which the glossary says increases when emotion feels overwhelming.
-
Defence (D)3
Illustration: she then laughs, says "Anyway, it was ages ago" and changes the subject: a strategy "used to avoid painful emotions", the defence corner.
-
Working back down the triangle3
Illustration: the therapist gently notes the shift and stays with her, the anxiety settles, and the sadness can be felt through to its end, as the glossary describes working with defences to reach adaptive emotion.
-
Metaprocessing questions3
After a shift the therapist asks things like "What's it like to feel this relief?", "What do you notice has changed?" and "What does this say about you?"
-
Post-breakthrough and mastery affects3
Relief, "feeling lighter, clearer, stronger"; and pride and joy, which come when fear and shame have been transformed.
-
Healing and tremulous affects3
Gratitude and tenderness toward the other and feeling moved; and fear mixed with excitement, curiosity, and "a feeling of positive vulnerability".
-
Core state3
The client reports calm, vitality and a sense of wellbeing, deeply in touch with themselves and the other person.
The four states
-
State 1: Stress and defence3
Defences, anxiety and dysregulated feeling, alongside first glimmers of resilience.
-
State 2: Processing core emotion3
Categorical emotions, attachment experiences and authentic self states are felt through in the body.
-
State 3: Metatherapeutic processing3
Client and therapist reflect on what just shifted, which brings its own transformational feelings.
-
State 4: Core state3
An open, calm state of contact with self and other, often with compassion, vitality and a coherent story of oneself.
How a session works
-
A safe relationship2
The therapist co-creates a relationship that works as a safe haven and secure base for in-depth work with painful emotional and relational experience.
-
Tracking emerging feeling1
The therapist tracks emotion moment to moment so the client can experience previously blocked feelings in a regulated way, through to completion.
-
Metaprocessing3
When something good shifts, the therapist asks what it was like to experience it: the change becomes the focus of the work.
-
"Rigor without shame"2
Fosha's phrases for the stance include "existing in the heart and mind of the other" and being a "True Other".
What the research says
-
Private-practice study5
62 self-referred adults in five countries had 16 AEDP sessions; large pre-post effects and mostly reliable change were reported.
-
Gains held a year later6
Follow-up found gains were kept at 6 and 12 months, with larger effects for people with more severe problems.
-
What was excluded2
Those studies excluded active suicidality, addiction, psychosis, bipolar disorder and current crises, so they say little about those groups.
-
Limits4
The AEDP studies are naturalistic, co-authored by the founder, and the randomised trials the Institute lists test affect-focused psychodynamic therapy generally, not AEDP.
